Acid-mediated ring-transformations of 5-alkylidene-2,5-dihydropyrrol-2-ones, available by cyclization of 1,3-diketone dianions with bis(imidoyl) dichlorides of oxalic acid, resulted in formation of functionalized pyran-4-ones, such as 5,6-dihydrobenzo[h]c
Efficient synthesis of functionalized 2-carbamoylpyran-4-ones by ring-transformation of 5-alkylidene-2,5-dihydropyrrol-2-ones
